The present invention relates to filing appara- 75,883, filed April 22,1936, now Patent 2,231,029,

February 11, 1941.

An object of the present invention is to provide improved card retainingrail structures, adapted to perform certain new and improved functions.

A further object of the invention is to provide card retaining meanswhich makes it possible tosecure certain of the cards upon the drum in01T- set or staggered relation to other cards, so that the former arepositioned in a conspicuous mannor for ready acces by an operator.

A further object of the invention is to provide improved card retainingrail shapes and cards having novel slots therein adapted to cooperatewith the rails, to secure the cards thereon in an improved manner.

, A number of preferred embodiments of the invention are shown in theaccompanying drawings, but it must be understood that the invention isnot limited to the specific details of construction shown herein anddescribed below, as many modifications will readily occur to one skilledin the art, from a consideration of the disclosure of thisspecification.

In the drawings:

Figure 1 is a transverse section through the rim of a filing drum inaccordance with the present invention, showing one form of cardretaining rail.

Figure 2 is a similar view showing another form of rail.

Figure 3 is a similar view of still another form of rail, and

Figure 4 is a view of another modification in which the cards may bemounted in staggered or offset relation.

This application i a continuation-in-part of my application, Serial No.386,326, filed April I, 1941, since matured into Patent No. 2,316,439,Aprill3, 1943.

As disclosed in the aforesaid patents and in my Patents No. 2,332,605,No. 2,332,606 and No. 2,316,489, filing drums of the type with which thepresent invention is concerned comprise a pair of drum heads which maybe formed of stamped or spun metal and a cylindrical rim I prefer- Icard, indicated in dotted lines.

14 Claims. (Cl. 129-46) ably constructed of cast aluminum, suitablymachined and having its marginal flanges IOI, I02 secured upon shoulderportions of the drum heads by tie-bolts which draw the heads togetherand firmly clamp the rim in place. Since the invention of the presentapplication is not concerned with the drum structure, only the rim andassociated part are shown in the accompanying drawings. The drum as awhole is mounted for rotation about a horizontal, inclined, or verticalaxis, in a well known manner.

As shown in Figures 1 and 2, the rim I00 is provided with one or moreradially projecting rails, each or which may be continuous entirelyaround thedrum periphery or interrupted and provided with removablesections, as described in my Patent No. 2,316,489. The rail comprises aweb I30 having side faces I3I, I32 which diverge in an outward directionfrom the periphery of the drum to the head I 33, to produce a wedgeeffect upon the margins of the slotted throat of the At the outer endofthe diverging portion of the rail web, the head I 33 is positioned,defined by arcuate side faces I34, I35 and an upper of outer arcuatesurface I36. As shown, the side faces I34 and I35 are struck aboutspaced centers on arcs of equal radius. The outer surface I36 isdisposed on a flatter arc, struck about a diiierent center on a longerradius. I This construction provides a line contact with the cards ofincreased length, and the head positively prevents the cards from ridingoutwardly'and becomin tightly wedged to the rail web. The elongated,relatively flat arc I36 at the outer end of the rail head provides anelongated bearing surface for the cards, when the cards are tippedrearwardly or forwardly for inspection or the like. Moreover, theelongated bearing surface maintains the cards in alignment andfacilitates finding the cards.

In Figure 2, a Slightly different form of rail is shown, in that thehead I40 at the outer end of the outwardly diverging "side walls I4I,I42 is laterally enlarged to a lesser degree than in the form shown inFigure 1. However, it will be noted that the side faces are again formedon arcs of verge on a smaller angle.

thicker than the web in the first two forms of the invention, and theside walls I5I, I52 di- Further, the side faces I53, I54 of the head I55join the outer end face I56 on arcuate, curves I51 of short radius,instead of intersecting theouter surfaces as in' -Figures l and 2.Surfaces I53 and I54 are disposed, in

section, on arcs struck about centers I58, I59 re-.

spon'dingly' shaped margins: of an enlarged portion of said opening inthe card.

- 2. A rotary filing drum comprising a substantially cylindrical rimhaving a card retaining rail projecting outwardly therefrom and arrangedcircumferentially of the rim, said rail having a which mergetangentially with the inner and outer rail head surface are struck aboutcenters I6I,onshort radii.

The slot cut adjacent the inner edge of, the card includes a throat I1Ihaving margins parallel to the side faces I5I, I52 of the web I50; andan inner enlargement; I13 havin side margins I14, the lower portionsofwhichareconcentric to the side faces I53, I54 ofthe; rail head. Theupper margin I15 is spaced outwardly a-substantial distance fromtheouter surface, I56 of the rail head, to permitv the card-t betippedrearwardly or forwardly, and iscut on an arc'having a radius equal inlength to the radius of thearc of surface I56. Thus, when the cards arestanding radially on the drum, they are retained by a. line contact withthe rail of substantial length, and-whenthey are tipped forwardlyorrearwardly, they engage the outer face of the rail head overasubstantial area.

web portion defined by side faces diverging outwardly in cross sectionfrom the rim, and a laterally enlarged head having convex side and topfaces disposed in cross section, on arcuate curves I struck about spacedcenters.

As a result of the combination of the diverging side walls of'the webandthe laterally enlarged head at the outer end thereof the holdingpower of the. rail on the cards is increased andthe rail as a whole maybe of. lesser heightor radial-dimension than in other cases.

In Figure-4 there-is shown amodified. form.of

drum and card retaining rail adapted to secure a plurality of cards upontheperiph'eryof the drum in axially staggered relation. In this case,

the card retaining rail 95 projects axially from a drum head 96,Which-may be integral-with the rim 91 or formed separately. Thus, the.rail 95 is disposed in concentric spacedrelation to the rim. The railhas two or more enlargements 98, 99, the upper surfaces of which, may.bearcuate, and the lower or radially inner surfaces inclined anddiverging from the outer surfaces, as previously explained. Cards havingsimilarly shaped slots may be secured thereon in staggered relation asindicatedin Figure 4. This type of card retaining means is particularlyuseful in cases where the drum is mounted for rotation on asubstantially vertical or inclined axis. It provides means for firmlysecuring the cards to the drum and for offsetting certain of the cards,axially relative to the others.

Although the invention has been described with considerableparticularity by reference to the embodiments shown in the accompanyingdrawings, it must be understood that it is not lim- 3.
